I was reading the alignment procedure for a model 48-482 radio, an output meter is to be hooked up to the #3 ant. terminal for aligning. What is an output meter?

As I recall, that is simply a connection to the speaker (af xfmr secondary) and you can use an AC VTVM just as you would normally. They just put it in a more convenient location so that you don't have to tap into the spkr wiring.
